'- ghee E AEEN'E' QFEEQE STREET-SERVICE STRUCTURE Hans Beiehert, Berlin, Germany Application April 7, 1937, Serial N 135,578 In Germany April 9, 1836 1 Claim. (CL 189-2) square cross-section is larger than required for the accommodation of a single person, and extra space must be provided for opening the door to- I 1 Ward the inside, or the outside, of the structure- The ground floor space occupied by the usual square structure is too large and often prohibitive, where space is limited.

It is an object of my invention to provide an improved street-service structure which is without the drawbacks of the usual structure, requires minimum ground floor space, and has a door which does not give trouble.

To this end, I design the structure as a tubular column, of circular cross-section, and equip it with a. door mounted to slide on the column in turning about the am's of the column.

In the accomparnaing drawing, a street-service column embodying my invention is illustrated 30 more or less diagrammatically by way of example.

In the drawing Fig. 1 is an elevation of the column,

Fig. 2 is a section on the line III-II in fig. 1,

Fig. 3 is an axial section of the columns base,

showing the elevator, and

Fig. 4 illustrates a loud speaker on the column.

Referring now to the drawing, and first to Figs. 1 and 2, l is a parallel tube of circular cross-section which will be referred to as the principal section oi the column, and is of sheet metal, or any other suitable material. 22 is the base of the column which is also of circular cross section but whose diameter is greater than that of principal section f. The base is below the street level SL. 23 is a narrow beveled annulus at the top of the base 22, for supporting the principal section l- IB is the roof of the column, shaped like an inverted dish, with a vertical flange which is spaced from the principal sectiom and l t are lamps on the underside of the inverted roof in the annular space between the flange and the principal section 1. Obviously, the roof must not project too far beyond the principal section 55 f, as this would spoil the appearance of the column. In practice, for a column which is 16 feet high, the width of the annular space is about 7 in. The roof it! supports a loud speaker 5 and a clock frame 8.

2 is a telephone cell in the lower portion of sec- 5 tion l, just above street level S, and the floor of the cell is the top plate I of an elevator I which is concealed in the base 22, as will be described. The cell 2 is equipped with a. telephone 3, an emergency device 4 for calling the police or .a rescue station, the fire brigade, etc. being arranged at one side of the telephone.

5 is the door of the cell. It is not hinged but is mounted to slide on the wall of section I in turning about the axis of the column. Ed is a handle for pushing the door to the right when it is to be opened. Preferably, the frame of the door 5 is partly cut away and glass panes are inserted in the recesses. A window 6 is arranged opposite the door 5.

Under modern trafiic conditions, structures of the kind described are practically indispensable but space conditions are often prohibitive. My column, on the other hand, is specially designed for restricted space. in that it is circular in crosssection and therefore smaller than the usual square section, and in that it has the sliding door which in all positions is flush with the wall of the section I. A hinged door opens either inside, or outside, and in the first instance the cell must be made comparatively large as otherwise the door cannot be closed from the inside.

If the door opens outside this must be considered by distancing the structure from the nearest curb,

or other object, for about the width of the door, which is often impracticable. Apart from this the door while open is a great nuisance to passers-by. All these drawbacks are eliminated in my column whose sliding door 5 cannot give trouble as it does not project anywhere and therefore the 49 column can be placed quite near to curbs, houses, trees, and other objects which would prevent the operation of hinged doors.

My column is particularly suitable for supportlug, or housing, certain accessories. As men- 5 ti oned, anelevator 1 whose top plate 1' is normally the floor of the cell 2, is concealed in the base 22. Hydraulic means l2, Fig. 3, actuated by a motor-and-pump unit 13, control the elevator and, in turn, are controlled by switches, push but- 59 tons, levers, etc, inthe cell 2. By these means,

' the elevator is raised into the cell 2, and lowered again, as desired. The elevator holds a. folded portable stretcher I 5, and a medicincchest l8, which are exposed by opening the sliding door Hi. When the elevator is in its topmost position, the stretcher and the chest are removed through the opening of the door 5. The upward movement of the elevator is so limited that the telephone and other equipment can still be used after the top plate 5' has moved to the upper end of its stroke. The door 5, being not hinged. is not in the way and the space in front of the column is unobstructed so that the stretcher is easily handled.

The size of the elevator E, and the arrangement of its operating means, should be so determined that the elevator is a self-contained since it must move upwards into that portion of the telephone cell 2 only which is not occupied by the equipment of the cell.

Preferably, the elevator I is of the platform type, that is, the members by which it is reciprocated, act as its guides at the same time, and the space above the top plate l is not obstructed by extra guiding means. In other words, the olevator, in its topmost or active position, projects freely into the telephone cell 2.

Other accessories supported by the column are the clock frame 8, and the loud speaker I! which is placed on the roof 18 at the centre thereof.

gates 20, 2!. The trumpet of the loud speaker extends therefore as far as the vertical flange of the roof is. The means for operating the loud speaker are preferably arranged in the section i above the telephone cell 2.

This space can also be utilized for housing the hydraulic means by which the elevator is operated, or part of such means, if there is no room for them in the base 22. Thus, the motor of the unit 3, or the complete unit, can be arranged A above the cell 2, and pipes and cables are prefcrably arranged between the inner wall of the section i and a suitable lining, or, better still, in

5, are available for sticking posters.

Iclaim:

In a street-service columnwhich is of circular cross-section and defines an inlet opening, a roof plate atthe upper end of the column, a loud speaker secured centrally to the roof plate, and sound-directing means partly constituted by the roof plate.
